Arguments
x,y
x and y coordinates of nodes of the voronoi mosaic. Each node is a
circumcircle center of some triangle from the Delaunay triangulation.
node
logical vector, indicating real nodes of the voronoi
mosaic. These nodes are the centers of circumcircles of triangles with
positive area of the delaunay triangulation. If node[i]
=FALSE
, (c[i]
,x[i]
n1,n2,n3
indices of neighbour nodes. Negative indices indicate
dummy points as neighbours.
tri
triangulation object, see tri
. area
area of triangle i. area[i]
=-1 indicates a removed
triangle with area 0 at the border of the triangulation.
ratio
aspect ratio (inscribed radius/circumradius) of triangle
i.
radius
circumradius of triangle i.
dummy.x,dummy.y
x and y coordinates of dummy points. They are
used for plotting of unbounded tiles.
